Dielectric Properties of ZrO₂ Doped on NiO at High Frequency

Abstract:

Zr_xNi_1-xO was prepared by conventional solid state reaction. The properties of undoped and ZrO₂doped NiO ceramics have been studied. The raw mixture of ZrO₂and NiO were ball milled for 24 hours. The samples were calcined at 1000°C for 2 hours, pressed into pellet shape at 200 MPa and sintered at 1300°C for 10 hours. The sintered samples were subjected to XRD, Scanning Electron Microscopy (SEM) and Impedance Analyzer for phase identification, microstructural observation and dielectric analysis. The grains size decrease with the increment of dopant amount. Enhanced dielectric constant was observed in the ZrO₂doped NiO with x= 0.02 for the frequency range from 1MHz to 1GHz. The dielectric constant of sintered Zr_xNi_1-xO decreased with an increasing frequency. The result indicates that Zr ions have effectively changed the dielectric properties of NiO.Keywords: NiO, Zr-doped, XRD, SEM, Dielectric.
